Functional and Aesthetic Rehabilitation of an Endodontically Treated Tooth Using a Custom Cast Post and Core: A Case Report.

Endodontically treated teeth often exhibit significant loss of tooth structure, resulting in reduced mechanical strength and increased susceptibility to fracture. Post and core restorations play a crucial role in providing retention for the definitive coronal restoration and in reinforcing the remaining tooth structure. Among the various post systems available, custom cast post and core restorations offer superior adaptation to the root canal morphology, particularly in teeth with extensive coronal destruction or irregular canal configurations. Their ability to provide adequate retention, resistance to functional forces, and long-term durability has been well documented. Appropriate selection of post systems based on remaining tooth structure, canal anatomy, and functional demands is essential for achieving predictable clinical outcomes. This case report illustrates the successful functional and aesthetic rehabilitation of an endodontically treated tooth using a custom cast post and core. It highlights the continued clinical relevance of custom cast post and core systems in selected cases despite the increasing popularity of prefabricated fiber posts.
